St Ives currently operates four underground mines accessed via declines and several open pits, a centralised administrative office, an engineering workshop and CIP processing plant.

Declared Mineral Resources at St Ives decreased by 490 koz primarily due to depletion and closure of the Leviathan, Formidable, Dianna, Minotaur and Britannia Footwall pits during 2012. The Mineral Reserves, inclusive of a depletion of 490 koz since December 2011, declined to 2.2 Moz (2.8 Moz at December 2011). Changes to Mineral Reserves from December 2011 were dominated by limited discoveries at Neptune and Cave Rocks, with nominal additions at Hamlet and Athena.

Continued exploration success and increased drilling of the mine’s extensive greenfields project pipeline has led to further discoveries at the Incredible deposit, which now extends over 600 metres on-strike and is still open to the north. Further work is planned in 2013 to grow the deposit’s continuity and resource confidence. The St Ives Life of Mine (LoM) has been maintained at six years to 2018.

This Technical Short Form Report reflects the latest LoM plan, coupled with an updated Mineral Resource and Mineral Reserve statement as at 31 December 2012.

Gold Fields – St Ives Gold Mine – Technical Short Form Report 2012  3 4. Geological setting and mineralisation

The Norseman-Wiluna Greenstone Belt, which forms part of the Paleo-Neoarchean Yilgarn Craton in Western Australia, is a highly mineralised granite-greenstone terrain with world- class deposits of gold and nickel.

The Kambalda-St Ives region is part of the Norseman-Wiluna Location and geological setting Greenstone Belt, which comprises regionally extensive volcano-sedimentary packages. These were extruded and deposited in an extensional environment and is part of the Yilgarn Craton, a 2.6 Ga well mineralised granite-greenstone terrain in Western Australia. The rock types in the belt comprise abundant tholeiitic and komatiitic volcanic rocks, chert, sulphidic and albitic sedimentary rocks, and a chain of discrete felsic volcanic centres.

The gross structure is markedly linear with strike-slip faults trending north-north west, and other tectonic lineaments traceable for hundreds of kilometres, which disrupt the greenstone into fault-bounded domains. The generalised stratigraphic sequence comprises three mafic-ultramafic units, two felsic volcanic units and an uppermost epiclastic sequence.

There has been a complex and long-lasting history of structural deformation incorporating up to seven significant stages (D0-D7) during and after regional metamorphism. The gold mineralising episodes are interpreted to have occurred during thrusting and faulting associated with the D2-D3 Schematic of gold mineralisation occurrences structural events.

On-mine exploration: Milestone pyramid

St Ives maintains rigorous QA/QC protocols on all its exploration programmes. It draws on industry best practice for data acquisition and utilises accredited laboratories which are regularly reviewed both internally and externally. Analytical QA/QC is maintained and monitored through the submission of blanks, certified reference material and duplicates plus umpire laboratory checks. This ensures sign-off by Competent Persons under the 2007 SAMREC and 2012 JORC Codes.

5. Mining

Conversion to open pit owner mining was completed in 2012.

Gold mineralisation at St Ives is mined using open pit and drilling and blasting. In such projects, hard rock is imported underground methods to depths generally not exceeding for sheeting to facilitate the access of equipment during 500 metres below surface. As many of the operations involve mining, and/or dewatering of the sedimentary overburden mining deposits on or under Lake Lefroy (a shallow salt lake), prior to mining. extraction requires the construction of berms and other earthworks to facilitate access, provide short-term stockpile Load-and-haul is carried out by 140 tonne dump trucks and areas and prevent water intrusion. 150 to 250 tonne excavators in backhoe and/or face shovel configuration.

Mine planning and scheduling The Mineral Reserve definition processes are similar for open pit and underground operations. Cut-off grades are used to define potentially economic mining panels, taking into consideration direct mining and processing costs, Group set commodity prices and other parameters. The economic viability of future mining panels is tested by determining whether the optimal margin, after applying the appropriate cut-off grade, is sufficient to cover the required capital development costs and provide a return on investment.

Open pit optimisation software in conjunction with economic parameters and physical constraints is used to generate a series of nested pits for open pit mining. An optimal shell is then selected and a detailed design used to confirm the mineability.

Underground mines at St Ives are commonly extensions of Underground mining methods are largely determined by open pit mines. Underground operations are characterised by the geometry of the mineralised zones and evaluation may common features which allow a high level of standardisation involve review of more than one method. Sophisticated in operating strategy, mine design, stoping methods, mining software is used for mine design and scheduling. equipment and utilisation.

Gold Fields – St Ives Gold Mine – Technical Short Form Report 2012  9 9. Mineral Resources and Mineral Reserves

Geology and evaluation models have been updated to reflect the latest available data sets. An integrated mine design and schedule plan is based on current performance levels and takes cognisance of the inherent risks associated with mining operations at St Ives.

The Mineral Resources are classified as Measured, Indicated and Inferred as defined in the SAMREC Code. Increasing levels of geo-scientific knowledge and confidence are based on geological understanding, grade variance, drill hole/sample spacing, mining development (amount of exposed and mapped mineralisation) and mining history. The economic evaluation is based on the gold price specified by Gold Fields, taking into account estimates of all costs, the impact of modifying factors such as mining dilution and metal/ore recovery, processing recovery and royalties.

Mineral Resources The Mineral Resource statement for St Ives is summarised in the tables below. The impacts of year-on-year changes are discussed in the reconciliation section.

The following factors apply to the Mineral Resources presented in this report:  Mineral Resources are quoted at an appropriate in situ economic cut-off grade, with tonnages and grades based on the relevant resource block models. The Mineral Resources also include estimates of any material below the cut-off grade that need to be mined to extract the economic portion of the Mineral Resource;  100% attributable to St Ives Gold Mine; and  Surface sources include stockpiles and are supported by adequate sampling, and are thus classified as Measured Mineral Resources.

Modifying factors  The Measured and Indicated Mineral Resources are inclusive of Mineral Reserves.  All Mineral Reserves are quoted in terms of run of mine (RoM) grades and tonnages, as delivered to the metallurgical processing facilities, and are therefore fully diluted.  The Mineral Reserve statements include only Measured and Indicated Mineral Resources, modified to produce Mineral Reserves and are contained in the LoM plan.  Mineral Resources and Mineral Reserves undergo regular internal and/or external audits, and any issues identified are rectified at the earliest opportunity – usually during current reporting cycle.

Mineral Reserve sensitivity Underground at Hamlet To illustrate the impact of fluctuations in gold price and exchange rates on the current declaration, St Ives has generated sensitivities with respect to Mineral Reserves. The following graph indicates the managed Mineral Reserve Sensitivity at -10%, -5%, Base, +5%, +10% and +25% to the gold price.

These sensitivities (other than for the base case) are not supported by detailed plans and should only be considered on an indicative basis; specifically as such sensitivities assume 100% selectivity, without any operating cost increases.

18  Gold Fields – St Ives Gold Mine – Technical Short Form Report 2012 12. Brief history

The history of St Ives

1897: Gold discovered at Kambalda Red Hill camp. 1897 – 1907: Other gold-bearing locations, such as Victory, discovered with an estimated total production of 31 koz, mostly from the Red Hill group of mines. 1919: New discovery led to construction of Ives Reward mine and small town in St Ives area. 1926: Ives Reward mine closed, having produced 10 koz of gold. Town abandoned. 1966: Iron-nickel sulphides discovered near the old Red Hill mine. Western Mining Corporation (WMC) acquired ground and developed a mining and milling operation. From 1966 to 1996 the region produced approximately 34.0 Mt of ore at an average grade of 3.1% nickel. 1970s: Increase in gold price led to a re-evaluation of the old gold prospects in the Kambalda area. 1980: Significant gold mineralisation identified beneath the Hunt nickel shoot. 1981: Discovery of the Victory-Defiance complex (Leviathan area). Gold production commences at St Ives using a 0.5 Mtpa treatment plant (later expanded to 1.2 Mtpa) located at the Kambalda Nickel Concentrator site. 1988: New 3.1 Mtpa CIL facility constructed 25 kilometres south of Kambalda at St Ives. 2001: 2.0 Mtpa heap leach facility commissioned. St Ives acquired by Gold Fields Limited. 2004: 4.8 Mtpa Lefroy mill constructed. Fully commissioned in early 2005. 2006: Start of aggressive exploration programme with full field aircore drilling programme. 2007: Start-up and establishment of Cave Rocks and Belleisle underground mines. 2008: Initiation of mining new consolidated Leviathan open pit. 2009: Discovery of new Athena-Hamlet deposit. 2010: Continued discovery growth of Hamlet deposit. Commencement of Athena mine with the first ore intersected in May 2010. 2011: Athena reaches commercial level of production in September 2011. Hamlet development intersects first ore in October 2011 as part of a new mine development programme. 2012: Stoping commences at Hamlet, Cave Rocks LoM extended and an early-stage discovery of a new camp (Invincible deposit). Conversion to open pit owner mining completed and heap leach processing stopped.
